to cultivatois, and

that class of cultivators straddle-row cultiits object, among others, to provide an improved construction based principally upon and designed as an improvement n the construction shown in Patent No. lt, i924.

having no pivotal move- I have that this arrangement does not allow sufficient lateral movement of the pivoted inside beams next to the plant row,

and to overcome provide the novel construction hereinafter described.

rlhe basic novel feature of the present construction provides in the pivoting of the outside beam so lateral movement, and in pivotally connect-` beam with whereby all beams are ing said outside beam and so on,

mounted to move in unison. one form of the invention upon its own 'individual or indepen that it is free for the'next adiacent- The beams in are mounted. each dent pivot and the inclinedV members connecting the `same pivotally join beams. By this means pable. of opening or This serves to give each two adjacent the beams are caclosing in fan-like the inside beams more lateral movement and less lateral movement of the outsi de beams which prevents the outside beams from coming in contact with the wheels.

Furthermore, the

outside beam serves to limit the lateral movement of the other beams, while the separatin g of the ground and guards against none beams enables me to cover all the being missed during the operation of the cultivatoi'.

The same result practically 4is obtained by mounting the two inside beams upon a common pivot and so connecting the outside beam pivotally with the inside beams to give them pivotal movement laterally relative to but also in unison with the outside beam. f

I aim further at improvements in the details of construction,

Other objects and advantages of the' invention will hereinafter appear and the novel features thereof will be particularly pointed The invention, in its clearly illustrated in out in the appended claims.

Figure 5 is a sideelevation of Figure 4.

Figure 6 is a perspective detail showing the manner of mounting the pivot of the memberA connecting the'beams.

Like numerals of reference indicate like parts throughout the several views.

Referring to the drawings 1 designates the tongue. 2 the seat mounted onthe cross member 3, and 4 the frame from the rear ends of Awhich said cross member 3 is supported. 5

are the wheels, mounted on the spindles 6,

angled ends 10 of the yoke 11, the transverse port-ion of which extends beneath the rear end of the tongue. All of these parts are well known or of any approved form of construction and of themselves formv no part o the present invention. l

Referring first to Figures 1, 2 and 3, 12 designates the outside beam and 13 and 14 the inside beams 'of which latter there may bev more orless as may be desired. The outside beam 12 is mounted upon a pivot 13 supported in the bracket or member 15 on the angled end 10 of the member 11, any suitable form of connection being employed as may be found most desirable. When two inside beams are employed, such as 13 and the two are united in any suitable manner as, for instance, by being bolted to the casting or member 16 carrying the pivot 17, which is mounted in the member 15, .all of which is'clearly shown in Figure 3. In order that the outside beams 12 and the inside beams 13 and 14 may be ioined so as to move in unison, I employ `the bar 18, one end of which is fastened to the outside beam 12 near its outer end, as seen at 19, and its other end connected as at transverse member 8. 9 are braces connecting the tongue with the instance,

` engaging members 32 will desired. As the beams 20, with one or the other inside beams 13 and 14 (see Fig. 3). This member 18 may be connected to either one of the beams 13 or 14 as may be found most desirable, the result being practically the same, regardless of whichever one of vthe inside beams has connection with said member 18.

In order that the relative positions-of the beams may be changed I mount the pivots of the member 18 in a member 21 (see Fig. 6), which member slidably receives the member 18, the meu'iber 21 being designed to be securedy in its adjusted position by suitable means, as'the bolt 22 (see Fig. 6).

While the sets of beams at each side of the cultivator may be moved upon their pivots upward inany way, I have chosen to show in the present' instance an eiiicient form comL prising a rod- 23 tor each set o1" beams attached at its lower end in any suitable manner, as at 24, to one of the beamsof a set andV at the upper end in anysuitable manner, as by hook and eye or the like, as shown at 25'.v to the member 26 which may be, for of the two-arm type, as seen in Figure 2, the 'forward ends of which are pivotally mountedy as at 27 in ears or the like 28, rising from the cross member 8, as shown clearly in Figure 2.

The operation will be readily understood upon reference to Figures 1, 2 andy 3. The

driver sits on the seat and with his feetk may easily swing the beams inward or outward as circumstances may require to clear the plants, the outer beams moving with the inner beams, the construction being such that it is not necessary for him to remove his hands from the'reins. Any suitable form ot foot rest 29 may be provided and the same maybe attached in any suitable manner to the beams, in' the `present instance being shown as mounted upon the brace member 30 connecting the beams 13 and 14, as seen clearly in Figure 3. It is evident, however', that anyeth'er form of foot restmay be employed and attached in any other manu ner to any convenient part of the device. Attention is cal-led to Figure 5- in which the foot rest 29 is shownA and secured to the curved portion c1 one ot the beams and having the opening 31 for the reception of the foot. This serves very eiciently as the foot rest, but any'other form may be employed.

enit is desired to raise the beams from the ground the rod 23 and the mem,- ber 26 is moved from the full line position, in Figure 1, t'o the dotted line position in sa-idigilire, when the beams and their earthbe elevated, as indicated by the dotted lines in said Figure 1.

The pressure of the foot of the driver tends to vmove the beams 12, 13 and 14 in unison either outward or inward as may be are moved upon their reuderingit much easier for pivots .the angle of the position ofA themember 18 is changed and this member 18 serves to limit the outward movement of the outer beam 12 so as to preventits contact with the wheel, and by' reason of the pivot connection of beam and with the inner beams, the movement of: the beams is accomplished with gradually lessening power or exertion as the beams are moved inward or into the dottedv line position inf Figurel 3. F orV ease of movement, that is, with theleast exertion on the part ot thev driver, the foot rest 'is placed upon the insidel beam and, in the present instance, between the two; beams 13 and 14, as seenbest in Figure 3;

As before stated, the angularly disposed members 18 pivotally connecting the inside and the voutside beams ment of the width of the bea-msor forl any desired angle 'or movement of the folding of the beams by merely sliding thev pivoted brace supports 21 lengthwise of the'bea-ms, tightening the bclt'22.A Y

The lever-like folding. et the beams permits kot greater lateral. movement of the inthe member 18 with the outsidev perm-itsy of. vadjustside beams with relatively. less movement of the outside beam, thus avoiding `unnecessary movement o-t the outs-ide beam and the driver to control.

1n .Figures 4 and 5 I have shown a slight'- ly modified' arrangement, but by' means of which practically the same result is ob tained. l Y

In these views the outside'beam `337is mounted upon a pivot 34, the. next adjacent inner beam 35 is mounted upon an individual pivot 36, while the next inner; beam 37 is mounted upon its own individual pivot 38. In this instance the pivots 34, 36 and 38 are all regulated by onemember 39 having lugs 40 mounted uponthe cross member 41 of the yoke 42. The beams 33, 35 and 37 may be connected each withits owny pivot member in any suitable manner andl the. outside beam is connected with the beam 35 by inclined members or member 42, while the beam 35 i's likewise connected with theV other beam 37 b v a simi-lar member 43, shown clearly in Figure 4, each end of the mem-bers 42 and 43 being mounted upon pivots 44 carried in the supports 21 providedwith bolts 22, as seen in Figures 5 and 6,- of the members 42' and 43 may be readily slid upon the beams for the same purpose as above described, vwith' reference to 'the form shown in Figures 1, 2 and 3. The foot rest 29 in this instance is secured tothe innermost beam 37, as seen in Figure 4, to obtain greatest leverage and of movement of the beams upon their pivots.

this form the beams can inward or outward as occasion may require, and as will readily be seenby reference to whereby the ends i 120 Figure 4, no ground will be missed in the yoperation of the device. The outermost beam is limited in its movement by reason of its pivoted connection with the next adjacent beam, and allthree beams are simultaneously moved upon their pivots 34, 36 and 58. The dotted line position in Figure 4 readily indicates the manner in which these beams are moved, and the relative amount of movement of the three beams.

In this form as in the form shown in Figures 1, 2 and 3, the beams may be moved simultaneously up or down by means similar to that shown in Figures 1 and 2, or by any suitable or convenient means.

Modification in detail, proportion and relative arrangement of parts may be resorted to without departing from the spirit of the invention or sacriiicing any of its advantages. j

What is claimed as new is:

1. In a cultivator, a pivotally mounted outer beam, an independently mounted 1nner beam and a member slidably and adjustably mounted upon one of said beams, and a member disposed inclinedly angularly with relation to said beams and at one end pivotally mounted upon said slidable member and at the other end pivotally and slidably connected with the adjacent beam.

2. In a cultivator, a frame, a tongue, yokes, means connecting the angled ends of the yokes with the tongue, an outside beam mounted on the angled end of one of the f members pivotally inner beams mounted on the yoke, and rearwardly and outwardly inclined connecting the same and slidable along the beams with means for securing said members in any adjusted position .lengthwise of said beams, whereby the movement of the beams is accomplished with gradually lessening vpower as the beams are moved inward.

3. Inv a eultivator, beams arranged on both sides, members slidable along the beams, means for securing said members yin any adjusted position lengthwise of said beams, and a bar pivotally connected to the members on separate beams.

4. In a .cultivator, pivotally mounted beams arranged on both sides, members embracing the beams and slidable therealong, means for securing said members in any adjusted position lengthwise of said beams, and a bar pivotally connected to the members on separate beams.
